Luggage hardware hardness of electrophoretic lattice frame -B

2025-05-10

Fourth.hardness test methods and standards Luggage hardware commonly used test methods Pencil hardness test According to GB/T 6739 standard of luggage hardware, use a pencil of known hardness to scratch at an angle of 45°, and take the highest hardness value without scratch as the result. Vickers hardness (HV) for thin coatings (<50μm), the hardness value is calculated by the diagonal length of the indentation. Knoop hardness (HK) more accurate hardness measurement of small areas, suitable for localised hardening treatments. Luggage hardware standard references Automotive industry standards ( GMW 14872) require electrophoretic coatings to have a pencil hardness of ≥3H and a scratch resistance (under 500g load) of ≤3mm scratch width. Industrial equipment standards may be more stringent, HV ≥ 200. Fifth.hardness performance in practical applications Scratch resistance Hardness and scratch resistance are not linearly related. For example, a coating with HV300 may be scratch-free under a force of 5N, but a coating with HV250 may perform better with the addition of a lubricant (such as silicone oil). Environmental Adaptability High temperature and high humidity environments (such as 85°C/85%RH) may cause the coating to soften and the hardness to drop by 20-30%. Long-term hardness stability needs to be verified by ageing tests. Sixth.recommendations and directions for optimisation Process optimisation Adjust the pH (5.5-6.5) and conductivity (1000-1500μS/cm) of the electrophoresis solution to improve the densification of the coating. Adopt UV curing technology for the lattice layer, which can shorten the curing time to within 10 seconds and increase the hardness by 15%-20%. Luggage hardware material Selection For scenes requiring high hardness (outdoor signage), a combination of stainless steel substrate + epoxy electrophoresis + two-component polyurethane lattice frame is recommended. For lightweight requirements, aluminium alloy substrate can replace part of the electrophoresis layer function by anodic oxidation pretreatment (hardness HV300-400). Quality Control…

Hardness of electrophoretic lattice frame of metal logo-A

2025-05-10

The hardness of the ‘Engraved Round Metal Logo’ is a complex issue that involves a number of factors (such as the electrophoretic coating process, the way the frame is handled, the metal substrate, and so on), and it is not possible to give a fixed value directly. The following are the key influencing factors and analyses: First.influence of electrophoretic coating on hardness Metal logo coating type and thickness The hardness of an electrophoretic coating is directly influenced by the formulation and thickness. For example, epoxy resin-based electrophoretic coatings are usually hard , while acrylic resin-based coatings may be soft . The thicker the coating, the surface hardness may vary depending on the degree of curing, but too thick a coating is prone to internal stresses, which in turn reduces the actual scratch resistance. Curing process Curing temperature and time play a important role in hardness. For example, the curing of an epoxy coating at 180°C for 30 minutes is more harder than one cured at 160°C for 20 minutes. If curing is inadequate, the coating may be sticky or scratched easily . Second.enhancement of hardness by lattice treatment of metal logo Role of the lacquer layer A lacquer (such as acrylic varnish) acts as a transparent protective layer and enhances the surface hardness by 1-2 pencil hardness levels. For example, when the electrophoretic coating itself is 3H, it may reach 4H-5H after lattice treatment. Synergy between lattice frame and electrophoresis layer If the chemical compatibility between lattice frame and electrophoretic coating is poor, it may lead to insufficient adhesion between layers, limited hardness enhancement or even cracking. Compatibility needs to be verified by adhesion test (scratching method). Third.influence of metal substrate Metal logo substrate material Stainless steel substrates (304, 316) have a significantly higher hardness than aluminium alloys After electrophoretic…

There is no set standard value for the thickness of the electrophoretic lath (usually referred to as the electrophoretic coating or electrophoretic paint layer) for Metal Logo as it depends on a number of factors including but not limited to the product requirements, the environment in which it is to be used, the parameters of the electrophoretic process, and the characteristics of the material. However, a discussion of possible thickness ranges can be made based on industry practices and the general characteristics of electrophoretic coatings. First.general range of electrophoretic coating thickness We can control the thickness of an electrophoretic coating by adjusting the electrophoretic process parameters. In industrial applications, the thickness of electrophoretic coatings can vary from a few microns to tens of microns. As for applications of requiring higher corrosion and abrasion resistance, the thickness of coating may be on the thicker side. Second.factors affecting the thickness of electrophoretic coatings Metal logo product requirements Different products require different the thickness of coating thicknesses..can provide better protection and decoration. Metal logo usage environment If we use the metal logo in outdoors or in harsh environments, need to require a thicker coating to resist corrosion and abrasion. Electrophoresis Process Parameters Parameters (such as voltage, time, and paint concentration) affect the thickness of the coating. By adjusting these parameters, can control the the thickness of the coating precisely. Material properties The material and surface condition of the substrate also affect the adhesion and thickness of the coating. For example, a substrate with a rough surface may require a thicker coating for complete coverage. . Third.metal logo recommendations and opinions For Metal Logos As they are usually used for decorative and signage purposes, therefore the thickness of coating should be sufficient to provide a good appearance and some protection, but not so thick…

The packing method of “Brand tag” needs to be comprehensively designed according to its usage, material, size and transportation requirements, and the core objective is to ensure that the label stays flat, dirt-proof and moisture-proof during storage and transportation, and at the same time is easy to use at the end. The following are packing strategies and operational details for different scenarios: First. basic packing material selection Moisture and anti-fouling layer Use transparent OPP self-adhesive bags or PE film to seal single labels to avoid ink or material deformation by moisture. If the label contains metal foil, hot stamping and other processes, additional wrapping bubble wrap or pearl cotton to prevent scratching. Support reinforcement layer Hard labels (such as acrylic, PVC) need to be separated by thick cardboard or EVA foam to avoid collision. Soft labels ( woven labels, stickers) can be rolled on a hard paper tube and fixed with winding film outside. Batch packing 50-100 labels as a group, packaged in kraft paper or corrugated box, filled with shredded paper or air column cushioning. Valuable labels (such as luxury goods tags) are recommended to be packed independently and then into customized foam boxes. Second, transportation protection program Anti-extrusion measures The carton size should be 5-10cm larger than the label set, and the interior should be filled with bubble wrap or inflatable bags to ensure that there is no space for shaking. Shaped labels (such as three-dimensional hot stamping) need to be customized foam grooves to fix the position of each product. Anti-static treatment Electronic labels (such as RFID chip labels) need to be packaged in anti-static bags, the outer box labeled “anti-static” logo. Extreme environment response When exporting to high temperature and high humidity areas, the outer box should be covered with waterproof film and desiccant should be…
